Some observations on the chlorination of nickel 200, hastelloy N, and inconel 600 in the presence of sulfur.
Mater Perform 1976 Apr; 15(4):25-27
Influence of sulfur additions to chlorine environments on the corrosion rate and persistance of rate changes from 433 deg to 727 deg c on ni 200, hastelloy n, and inconel 600 are reported. Persistence of the accelerated attack is attributed to increased permeability of the nickel chloride scale caused by sulfur which was retained in the scale as a nonvolatile species. Normal chlorination attach rates were resumed only after sulfur contaminated scale had been volatilized in an inert atmosphere. Chlorination rates of hastelloy n and inconel 600 exceeded that of ni 200, but were not changed by sulfur.
